Blackboard eraser

Abstract

The invention discloses a blackboard eraser which comprises a blackboard eraser body, a cleaning portion and a waterproof temperature sensor. The cleaning portion is mounted on one side of the blackboard eraser body. The blackboard eraser is characterized in that a touch display portion is mounted on the other side, opposite to the cleaning portion, of the blackboard eraser body; a cooling metal bar is arranged on the periphery of the display portion in a surrounding mode; a locking portion is further arranged on the surface, on the same side of the touch display portion, of the blackboard eraser body; a touch function is locked through the locking portion; a battery portion is arranged inside the blackboard eraser body; buffer rubber strips are arranged on the peripheries of the blackboard eraser body, the display portion and the cooling metal bar correspondingly and enable the interior of the blackboard eraser body to be airtight and capable of preventing dust and water; and the blackboard eraser body is further provided with a soundwave sound control portion, a sound prompt and lighting device is triggered through the soundwave sound control portion, combined functions are achieved, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to an intelligent blackboard eraser. Background technique [0002] Blackboard eraser (or whiteboard eraser) is a common tool in classrooms or conference rooms, and even gradually entered into the family. However, the existing blackboard eraser has a single function, especially when teachers are writing on the blackboard, they usually hold the blackboard eraser in one hand. Hold chalk in one hand to write on the blackboard. At this time, if the blackboard eraser has display and information prompt functions, the teaching efficiency can be greatly improved. At the same time, considering the convenience of operation and efficiency, as well as the harsh use environment in schools, the blackboard eraser should have multiple functions. interactive mode, waterproof and dustproof function, and excellent heat dissipation capacity. Considering that there are many classroom users, the bla...

[0002] Blackboard eraser (or whiteboard eraser) is a common tool in classrooms or conference rooms, and even gradually entered into the family. However, the existing blackboard eraser has a single function, especially when teachers are writing on the blackboard, they usually hold the blackboard eraser in one hand. Hold chalk in one hand to write on the blackboard. At this time, if the blackboard eraser has display and information prompt functions, the teaching efficiency can be greatly improved. At the same time, considering the convenience of operation and efficiency, as well as the harsh use environment in schools, the blackboard eraser should have multiple functions. interactive mode, waterproof and dustproof function, and excellent heat dissipation capacity. Considering that there are many classroom users, the blackboard eraser should also have a tour function. In order to solve the above technical problems, the invention provides a multifunctional smart board eraser with Dust function, which can solve the problem of incomplete use of the existing ordinary blackboard eraser, the inability to meet the multi-functional use mode and the function of peace of mind, thus greatly reducing the work intensity of the lecturer and improving the teaching efficiency
